The logical navigation definitely works better if Pod Security admission
and PodSecurityPolicy are pages in the same section. Make It So.

This list appears to name binaries whose configuration flags are documented in this section: [Command Line Tools Reference](/docs/reference/command-line-tools-reference/). Since kube-proxy is an item in that reference, it seems helpful to give it an entry and link here.
This PR fixes two problems. One was introduced by f265aed794
which folded the extend-cluster.md content into section index without
removing the original content. Another problem is that the PNG images
stored on google docs are not accessible by some people from the far end
of the planet.
Readers from several different backgrounds will find it useful to know
about how Kubernetes controls access to its API. Promote this overview
to the Security subsection of Concepts.
Where an existing Concept section has an index and the first page is
“Overview of X”, move the content of that overview into the index page
itself.
Also, configure redirects accordingly.
